Results represent contribution to understanding of the processing aptitude of meat from entire males and immunocastrates for high quality dry-cured products, which is not well explored. The study was publisehd in world leading journal on meat science.

The effect of adding hydrolysable tannins to the diet of fattening boars was studied on performance, reproductive organ weights, salivary gland morphology, boar taint compounds and skatole metabolism were. Adding hydrolysable tannins to the diet had no negative effect on growth performance up to 3% inclusion also resulting in an adaptive response of the salivary glands. Across treatments tissue skatole concentrations were proportional to the activity of hepatic CYP450, indicating potential of tannin supplementation to reduce boar taint.

In the present study the effect of hydrolysable tannins on CYP450 activities, gene, and protein expression in the liver and intestine along with properties of intestinal content was tested in fattening boars. Results show that tannin extract inclusion lowered intestinal skatole production, no general effect on CYP450 enzymes and suggest a potential effect (i.e. reduction) on androstenone synthesis.

Effect of high dietary fat content on heat production and lipid and protein deposition in growing immunocastrated male pigs was studied. The obtained results indicate that increased fatness of immunocastrate pigs is a result of increased daily lipid deposition caused by higher energy intake and lower basal metabolic rate. In addition, lipid deposition is further enhanced by dietary energy enrichment with fat after effective second immunization.

The objective of the study was to examine the effect of shorter or longer delay between effective immunization and slaughter on steroid hormones, boar taint compounds, and morphologic and histologic traits of reproductive organs. The investigated physiologic, morphologic, and histologic changes were progressive with the increasing delay to slaughter (clearly seen already 2 weeks after second vaccination), though no signs of functional or morphological restoration was observed within 8 weeks after V2.
